To all whom it may concern..-

Be it known that we, SAWYER D. CLARK and CHARLES F. BARTELTJ, citizensof the United States, residing at Boulder, county of Boulder, and Stateof Colorado, have invented certain new and. useful Improvements inVacuum-Producing Devices; and we do declare the following to be a full,clear, and exact description of the invention, such as will enableothersskilled in the art to which it appertains to make and use thesame, panying drawings, and to the letters and figures of referencemarked thereon, which orm a part of this specification.

, Our invention relates to improvements in vacuum producing devices, ourobject being to provide a construction adapted to be connected with afaucet through which water is drawn for household purposes, the ordinarysystem pressure only being employed.

Our improved device consists of a pipe connected with the faucet andextending downwardly a suitable distance, its lower extremity beingclosed and having openings above the bottom of the closure to allow thewater to escape. In our improved construe: tion a hood or shield isapplied to the discharge pipe and adapted to surround the portion of thepipe containing the openings, whereby the. water is prevented fromspreading over a large area] This hoodconfines the water and causes itto pass downwardly into the sink, or other apparatus through which itmay make its escape to the sewer. Connected with this discharge pipe isa conduit leading to the vacuum cleaner nozzle which engages the articlefrom which the dirt or dust is to be removed, The upper extremity of thedischar e pipe, as shown in the drawing, is provide with a removablenozzle which extends downwardly adjacent the opening with which thecleaner conduit is connecte Havin briefly outlined our improvedconstructlon, we will proceed to describe the same in detail, referencebeing made to the trating accompanying drawing, in which is illustratedan embodiment thereof.

In this drawing: Figure 1 is a view illusour improved apparatus shown incondition for use. Fig. 2 is a sectional view of the shown ona'largerscale. M

The same reference characters indicate'the same parts in all the views.

This nozzle reference being bad to the'accom-v discharge pipe andits connections shield 19, will be guided downward ..,sin'k 23providedwith a plpe leadmg to Let the numeral 5 desi nate a fixture faucet mayengage the upper extremity 8 of the e ector nozzle 9 which protrudesdownwardly into the member 10 of the part 9 is threaded into the upperextremity of the pipe member 10, adjacent the junction of the member 12with the -member 10. Connected with the part 12 is the flexible conduit13 ,whose opposite 'ex-.

' The lower extremity of the fixture 5 has a threaded connection, asshown at 15, with the upper extremity of the discharge pipe 16, to whoselower extremity is applied a sort of cup 17 which is threaded on thepipe extremity, as shown at 18. The lower part of this cup is closed,while its upper portion adjacent the end of the discharge pipe 16, isopen to permit the escape of the water after filling the cup 17.

It is evident that a great variety is connected with the cleaner nozofspecific constructions may be employed in carrying out our im rovement.The construction illustrated in the drawing, however, hasprovensatisfactory in actual use. Applied to the discharge pipe 16 andsurrounding the apertured portion of the. cup 17 is a shield 19 whichhas the shape of an inverted cup, its upper extremity having a collar 20which fits closely to the exterior of the pipe 16 and is held in thumbbolt or screw 21. This shield is vertically adjustable on the pipe 16,since the collar is slidable on said pipe and may be locked by the setbolt 21 in any position of adjustment.

When the device ,is in use, the faucet-is opened, whereby the water isallowed to enter the. member 10 of the fixture 5 and pass downwardlyintothe cup 17 which rapidly fills, the water then escaping through theopenings in the upper part ofthe cup. It is evident that in the absenceof a shield or housing, thewater would be discharged in all directions,through the openings 22. With the shield in place, however, the Waterissuing from the openings 22 striking against the walls of the invertedcup y into a -,shaped I place thereon by a necessary suction pull forcleaning purposes.

This is apparently due to the fact that the water backs up inthecup 17, and in combination with the tually seals the lower extremityof the discharge pipe l 6, or causes the water to escape therefrom withsuflicient force, to prevent the entrance 'ofair to break the suction.The

Having thus described our invention what we claim is:

As an article of manufacture for domestic a vacuum producing deviceadapted to be attached to a water spigot and to receive water underpressure, said device comprising an ejector having a discharge pipewhose upper end is adapted to be connected with the spigot, and has abranch pipe for connection with an air tube, and whose lower end isequipped with an enlarged closure which curves outwardly from the pipe,the upper portion of the closure being perforated for the escape ofwater discharged from the pipe thereinto, and the dome haped hood orshield open to the atmosphere at the water, the hood being applied tothe pipe and surrounding the closure in such proximity thereto that thewater issuing from,
